Power Supply 12 volts (full speed range operation). Quiescent current approx 1 amp. Max current 11 amps per hand-wheel (peak current under stall or max acceleration).
System Communications - Pocket PC to system - RS232; Camera to system - RS232 (ARRI435 etc.); Inter axis - RS485 two wire differential bus.
Automatic recognition of system configuration at start-up, with axis numbers and axis names displayed on Pocket PC. Axis numbers and names can be changed to suit the configuration.
Recording Memory - Type - Non-volatile eeprom, located in each axis. Ten year data retention. Size - Equivalent to almost 11,000 feet of film, or around 2 hours recording @ 25fps.
- Number of Recordings - 40, all name, scene, take, time and date tagged in axis memory.
- Max Take Length per Recording - 32000 frames.
- Recording Speed - 1 to 150 fps, locked to camera frame pulse. Recommended recording speed is >20fps. Also can record ramping camera speeds.
- Sampling Accuracy - Positions stored within 0.5 msecs. of start of frame pulse.
- Simulation - Camera frame pulses can be simulated at any speed from 1 to 150 fps with 0.001 fps accuracy.
Key frame Programming - on some or all axes. Can be tied in with previously recorded move. Up to 100 key frames with curve fitting algorithm.
- Playback Features
- Playback Dynamic Positioning Accuracy - frame to frame, measured at the hand-wheel, with a fully loaded head, at maximum playback speed. Equivalent to 0.075 degs. tilt axis, and 0.11 degs. pan axis.
- Static Accuracy - < 0.3 degrees at the hand-wheel.
NOTE:- Final accuracy at the head is dependent on the condition of the head, but has been found in practice to always be sufficiently accurate for all motion control applications.
- Playback Sync. - Axes locked to camera Frame pulse. Frame positions retrieved within 0.5 msecs. of start of frame pulse.
- Playback Speed - Any speed, including faster or slower than the recording (within the max speed constraint of the head servos), with camera frame pulses from 1 to 150 fps, including all non-integer values.
- Ramping camera speeds - from 1 to 150 fps, with the axes dynamically locking to the frame pulse. Pre-programmed ramps or manual ramps using an ARRI RCU.
- Playback Modes -
- Live Action, with 'multispeed' function. Play back at a fraction of the incoming frame pulse speed, or at a multiple of the frame pulse speed. One to ten times slower or faster in integer multiples.
- Time-Lapse - with motion blur, and controlling an ARRI SFC, or JWC DMS 120-S. Exposure range 1/8 th sec. to 15 secs. Intervals range 1 sec. to 70 minutes.
- Stop Motion - as time-lapse
- Forward or Reverse Playback
- Partial Move Playback with preroll
- Play to frame
- Record axes whilst playing back other axes
- Triggered Start record or Playback triggered by external input. Starts on next frame pulse after trigger.
- Gearing - Electronic gearbox range 99.9 to 1 down, to 1 to 30.0 up, in 0.1 increments. Simple setting via hand-wheel.
- Limit Stops - Hard end limits and soft limits, settable at any position, with user settable feathering rate.
- Head Brakes - Mechanical head brakes can be used as normal. System detects "brake-on" condition and prevents motor stalling.
- User Interface - Standard Pocket PC, running Pocket PC2002/2003. Graphical User Interface.
- Camera Control - ARRI 435/535/16SR3 and JWC DMS 120S. All camera functions, including reading and setting fps, shutter angle, foot count etc.
- Import/ Export - Text format move data files from / to CGI etc. Email moves via Pocket PC/ phone.
- Head Compatibility - ARRI head 1 and 2. An encoded head is NOT required. The servo control is sufficiently accurate to give precise move repeatability in all moco applications.
- Lens Motor Compatibility - Preston Microforce and FIZ units. Utilises existing Preston hand controllers, including wireless control.
- Field Upgradeable - Both the servo axes and Pocket PC can be firmware upgraded in the field, with simple and inexpensive programming tools.
